How do we create a hierarchal structures in our model? One approach is with the use of block definition diagrams! These diagrams are great as they are used at any …
Actor
An actor is a concept used to represent an external entity or system that interacts with the system being modeled. An actor can be a person, organization, or any other …
Creating Use Case Roles
Creating Use Case Roles can help describe actor initiated interactions with a system by identifying their role as either Primary, Secondary or Stakeholder. Primary actors are using the system to …

State Machine Diagrams
State Machine diagrams represent the behavior(s) of entities capable of dynamic behavior by specifying their response to the receipt of event instances. State Machine Diagrams are part of the family …
Lifelines and Sequence Diagrams
Lifelines and Sequence Diagrams focus on the interchange of matter/messages between system components. A Sequence diagram shows the interaction information with an emphasis on the time sequence. The diagram has …
Functions and Activity Diagrams
Functions and Activity Diagrams are representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency. Activity Diagrams are some of the most widely used behavioral …
Internal Block Diagrams
Internal Block Diagrams can help define the interface and characteristics of a system, as well as detail the communication between system elements. Often Internal Block Diagrams are perceived as a …
Blocks & Block Definition Diagrams
